held down the accellerator ( had to to move the arm away from the switch in the v glide ) kept clicking the microswitch and got clicks everytime from solenoid but still no movement............really seems now that what's affecting the darn thing is the removing and hooking back up power ?

Makes sense! Every time you pushed the micro switch,you de-activated the solenoid! So the clicking was the solenoid going off and then back on when you released the micro.

The spark earlier was because the caps in the controller did not have a chance to equalize voltage through the precharge resistor when you disconnected and reconnected the battery.

The resetting now points back toward the controller but still have to be sure that it is getting a solid input from the pot.

Wow, does my head hurt!!!!!!!!!!!

Okay,...well maybe we're getting somewhere

it's going to be the V glide pot, between the v glide pot or the controller???????????

So,...what do I start with tomorrow???????

LOL! Start with some coffee!

Yes it looks like it is going to be between the pot or the controller....or wiring in between...unless it's something else

Just don't give up! I bet you already learned more than you ever thought was involved in a golfcart! And I think we all learn along the way so it's good!

Beginning to understand why the 1998 CC's we have at the campground are resistors and not controller...even Club car was confused by controllers.

Okay,..had my coffee as suggested by 72VoltEZGO and now have just two plans for todays attempt at making this thing run.

#1. pulling the wires from the V pot to the controller and recleaning and maybe new contacts

#2. Try to adjust V pot to get 0 ohms at off throttle

if this works and I get no response...giving up the ghost and oredering new controller while I still have some hair left to pull out.

okay...this gets weirder and weirder

took the two marine batteries and hooked them up in the pack to make my 36volts

out of curiosity sake, just to see what today would bring me before getting into todays plans......tried to run the cart.........nothing

hooked up the charger and pushed on the pedal....it ran, let off the pedal...it ran...pushed on the pedal.....it ran switched between forward and reverse.....it ran..........unhooked charger.......it ran..pushed on pedal and let off on pedal and it's still runs .......now I'm afraid to touch it

going to let it sit awhile and see what happens later....maybe actually cut the grass or something

new discovery....thought I'd try this......hooked up all the batteries...run the cart...when it decides not to respond....I don't have to remove the battery cable and reconnect....I can just turn off power at the key and turn back on to get it to do whatever it's doing to run again.........seems like I average three times off the pedal before response dies.......sometimes 1 click of the key or sometimes 2 or 3 and then it runs again

something definitly resetting

now back to what I originally planned......making sure all contacts between v pot and controller are good and hopefully zeroing out the reading at pedal off

Using everybodys input and putting aside some of my stupidity for a few minutes....this is what I'm coming up with mentally....be ready to be impressed,...you're all great teachers.

My controller is apparently one of those with a High Input Safety DooDad ( made that last part up ). When I let off on the accelerator pedal easily, as you would when driving normally, at full off I get that high reading of 5.something something k going to the controller from the v pot. ( I only get 2.7 at full throttle when it's running and it does go up smoothly and runs fast as **** at the top end ). If I let the pedal slam back on it's own or pull back on it by hand after an easy release, even though I see absolutely no movement of the v pot arm, it goes to 0. It rests on the little bumper stopper thing which either way you do it.

So, apparently that high reading is telling the controller to shut down. Now either pulling and replacing a battery cable or using the ignition switch to turn off and on the power resets the controller?????????? and...depending on what the v pot is sending to the controller and that the controller actually reset, determines whether I run or not on the next attempt. And since it seems the longer and more times in a row that I attempt this, the less and less successful my attempts become because the controller gets pissed at me and becomes less responsive to my persistence. ( actually I assume it heats up or something because after letting it sit for awhile, it seems to become more responsive.)

Does this all sound good so far?

Now I'm thinking I have two options...........first would be preferably to figure out whats going on with the v pot. I checked the resistors and they all are very, very close to the resistance values listed in the parts manual. One question I do have is that the arm of the v pot at full on and off split the two copper plates at either end and not on the individual first or last plates. The bumper stop for full off is built into the v pot body so there's not much I can do for the low end anyhow. I have no idea why I get the reading that I do at low end or why pulling with a little pressure on the pedal resets the output to 0. THE ARM DOES NOT MOVE, I swear.

Number two option is I found rebuilt controllers for my cart that come with or without the High Input Safety DooDad......guess which one I'm thinking of buying!!!!


Does this all make sense. Thanks again.
